Energy harvesting system

An energy harvesting system for mounting on a towering construction, for harvesting energy from renewable resources, the system comprising:

• an array of wind turbines dispersed along said towering construction and configured to rotate when exposed to a wind load for converting wind kinetic energy into a different form of energy;
• a plurality of laterally outlying ledges branching outwardly in vertically spaced-apart respective levels, alternately lined-up along said towering construction above one of, below one of, or between two of, said wind turbines, wherein each of said ledges comprises:
• (a) at least one of:
• (1) an upper ledge surface which is slanted at a slope for deflecting ingoing wind upwardly toward an immediately adjacent-above wind turbine, and/or for diffusing outgoing wind downwardly away from an immediately adjacent-above wind turbine;
• and
• (2) a lower ledge surface which is slanted at a slope for deflecting ingoing wind downwardly toward an immediately adjacent-below wind turbine, and/or for diffusing outgoing wind upwardly away from an immediately adjacent-below wind turbine;
• such that each of said wind turbines is disposed below an immediately adjacent-above lower ledge surface and/or above an immediately adjacent-below upper ledge surface;
• and
• (b) a photovoltaic (PV) solar panel layout disposed at least on said upper ledge surface, said solar panel layout comprising at least one PV solar panel for absorbing and converting solar energy into electricity;
• and
• a gravitational energy storage module, configured to conserve the energy of the electricity produced by said wind turbines and said PV solar panels, by elevating a weighted load, configured to be lifted along said towering construction, to an elevated position, by the produced electricity, and allowing the weighted load to drop from said elevated position to a lower position for releasing kinetic energy, wherein the weighted load comprises an electrical/spring energy storing artifact, operational to store further electrical/spring energy produced by said wind turbines and said PV solar panels.
